CAR-WHEEL GRINDING AND TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 303,609, dated August19, 1884.

Application liled May 10, 19815.

Zo wZZ whom It may concern:

Be it known that I, W. P. BARCLAY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Grinding and Turning Machine, which isapplicable for grinding and turning the treads and flanges of car-wheelshaving either a chilled tread or a steel tire, the followingspecification and annexeddrawings describing and illustrating the novelfeatures of themachine, so that any one skilled in the art to which theinvention appertains could make and operate the same.

The'invention is more especially devised to overcome certain defects inthe manufacture of what are known as chilled car-wheels, the treads ofsuch car-wheels being of so hard at nature that the operation of turningthe tread and flange by the ordinary process of .i urnin g iron with asteel turning-tool becomes in'ipracticable from the expense accruingfrom such amethod.

In the accompanying drawings, Figure 1 representsa side elevation of themachine, and Fig. 2 is a plan View of the same. foregoing figures alsoshow a pair of carwheels, I, in posit-ion on their axle, supported bythe drivingheads of the machine. Fig. 3 is an increased transverseelevation of Fig. 1. Figs. 4c and 5 are elevation and plan views of thedriving-heads B, and are drawn on an increased scale. Figs. 6 and 6 areside sectional elevations of an abrading-tube, with its accompanyingspindles, slides, and columns.-

The abrading-tube is also shown protected by a cylindrical shield. Figs.6 and 6 are elevation and plan views, respectively, of Fig. 6. Figs. 7and 8 are elevation and plan views of the appurtenances which supportand operate the abrading-tube connected thereto, and Fig. 9 is alongitudinal sectional elevation of .Fig. 8 through the center 01' thebelt-pulley. Fi 10 is an end view of the grinding-face of anabrading-tube, and Fig. 11 is a side view of the same.

Similar letters of reference indicate corresponding parts throughout theseveral views.

Referring to the drawings, the bedplate of the machine is represented byletter A. The

other parts of the machine are supported by the bed-plate, and are allfirmly united to- The (No model) gcther by the necessary bolts. Thedrivingheads B are similar and duplicates of each other, and are securedto the bed-plate A by bolts 1) and cross-plates Z), the lower ends ofbolts 1) being firmly secured to the said crossplates. The car-wheels Iare shown in position on their axle, and the axle and car-wheels aremade to revolve with the spindles of driv ing-heads B. The spindles G ofthe drivingheads have each a faceplate, G. The faceplates are furnishedwith drivers that engage with the clamps that are secured to thecarwhcel axle, the car-wheels and axle revolving with the spindles O ofthe driving-heads when motion is communicated to the said spindles.Motion is communicated to the spindles 0, wheels D, pinions 1), shafts2, wheels E, and pinions E, connected with the driving-heads B bybelt-pulleys F, operating a worm, F, and worm-wheel F, which combinationcauses the shaft 3 to revolve, so that the respective wheels, pinions,and shafts immediately connected with each of the driving-heads, andwhich are shown definitely in Fig. 5, are all made to rev olve-together,and the corresponding wheels, pinions, and spindles of the driving-headsmake precisely with each other the same number of revolutions.

In Fig. 3 a transverse elevation of certain parts of the machine areshown. The column A is firmly bolted to the bed-plate A and upholds theseveral parts that are relatively constructed for suspending andadmitting all required movements to be given to the large abrading-tubeG. The columns A" support the lower sl ide-rests, H, and to the upperslideplate is connected'the base of pillows H, that hold the spindle J,one end of said spindle having a face-plate, J, and to which is firmlysecured the abrading-tube K. The hydraulic jack L is for the purpose ofraising and lowering the axles and car-wheels to and from the height ofthe centers of the driving-heads B. The hydraulic jack itself can alsobe lowered or raised bodily by moving it through the step L, which isfirmly secured to the beams N, the nut Lholding the hydraulic jack inthe position to which it is adjusted. Projecting from the nut L is asmall set-screw for tightening the said nut. \Vhen large and heavycar-wheels are placed in the grindingmachine,

they do not require to be lifted by the rain of the hydraulic jack sogreat a distance as car- Wheels of a less diameter, and the hydraulicjack is therefore suspended by the nut L and guided by the step L, so asalways to be in a vertical position. Vhen lifting large and heavycar-wheels, the hydraulic jack is held as high in the step L by the nutL as convenient, merely allowing clearance for the head of the hydraulicjack to pass underneath the axle of the car-wheels when the same are onthe axle and resting upon the floor or track. By so doing the rain ofthe hydraulic jack is allowed to remain in its working-barrel the utmostlength when lifting heavy loads.

J In Figs. 4c and 5 are represented the elevation and plan views of thedriving-heads, Fig. 5 showing the plan view of the driving-heads partlyin section. The driving-heads B have spindles C, to which thegear-wheels D are made fast. The face-plates Care also attached to thespindles 0. Each of the spindles C have inner spindles, O, and theyrevolve all together. The inner spindles, C, can be moved inalongitudinal direction by the screws S, operated by the hand-wheels XV.The inner spindles, G, are furnished with steel centers a, that projectfrom the face-plate ends of the spindles, and from the said centers aare suspended the axles with the car-wheels. The driving heads 13 haveeach two projecting arms, B and B. Pillows are formed for the shafts 2and 3 upon the projecting arms, and the driving-heads can be moved uponthe bedplate A, so as to be placed farther apart or nearer to eachother, to suit the different lengths of car-wheel axles. The pinions E,wheels E, pinions 1'), and wheels D move along with the driving-heads Bwhen the same are changed in position upon the bed-plate. The pillows 0have each a revolvingbush, O, that has a groove cut 011 the periphery ofits bore, so as to allow the revolving bush to slide along the featherformed upon the shaft 3. The pinions E have a projecting neck with acollar, 6. the collars working in recesses formed in the pillows O, tohold the pinions E always in the same relative position to the saidpillows, and when the driving-heads B require to be shifted in theirposition on the bed-plate the pinions E are obliged to move the samedistance along on the shaft 3-that the driving heads B have been shiftedalong the bed-plate A.

The small abrading-tube K with its connec tions are represented fully inFigs. 6, 6, 6, and 6. The abrading-tnbe K is secured to the faceplate J.The face-plate J and pulley J are shown as constituting a solid part ofthe spindle J, but would in actual practice be made separate andafterward secured to the spindle J by set-screws. The spindle J ishollow, and has a tubular bolt, P, passing longitudinally through thespindle. The head of the bolt is made as large in diameter as is convenient, so as to present a large bearing-surface to the flange thatprojects inwardly from the abradingtube K. The tubular bolt P has nutsP, and when theyare tightened the tubular bolt secures rigidly to thefaceplate J the abrading-tube K. An adjustable spindle, Q, fits tightinto the tubular bolt P, the said ad justablc spindle being use d as anextra support to the abrading-tube K when it is very long. Theadjustable spindle has a bolt, 1', passing longitudinally through itscenter, the said bolt having a tapered head, and when the nut I. on theend of bolt r is tightened the tapered head of bolt r wedges theadjustable spindle Q; to the position in which it is set, the saidadjustable spindle Q having at the end that the tapered head of bolt rfits into, several slits cut lengthwise of the spindle for a shortdistance, so that that end of the ad justable spindle can yield to thewedgingpressure of the tapered head of bolt 2- when the same is drawntight up by the nut t. The end of the adjustable spindle Q, that reachesinto the abradingtube K, has a large flange, and the nut t has a threadalso out upon its outer periphery. The ring a is tapered on its inside,and is cut through at an angle in one place. The nut o is tapered tocorrespond to the taper of the ring a, and as the nut u is screwed upthe tapered edge of the said nut springs the ring a to fit close to theabradingtube K, holding the end of abrading-tube rigid and free fromvibration, especially when the abrading-tube is of considerable length.The abrading-tubc K is shielded by a stationary cylindrical shield ofmetal, K. The shield K is supported by the adjustable arin K, and thebase of the pillows H has a recess that the lower portion of adjustablearm K can slide into the upper slide-plate, H, being so constructed thatthe adjustable arm K can be placed at an angle to the said slideplate orto the tread of the car-wheel. base of pillows H turns in thecone-shaped recess that is formed upon the upper slide-plate, H,whenever the arm K is caused to change its inclination to the saidslide-plate. The pillows H and the shield K, when adjusted to thedesired angle, are prevented from shifting around by screwing down theclamp-plate H by the set-screws r. The shield K and the arm K can beshifted in as the abradingtube K wears away, the lower portion of arm Ksliding into the recess a greater distance when forced. lVhen theinclination of the abrading-tube K to the car'whcel is changed, the armK changes to the same inclination, and holds the shield K alwaysconcentric with the said abrading-tube.

In Fig. 6 the dotted lines 1 indicate the greatest angle that the arms Kand shield K can be placed at to the slide-plate H.

The large abrading-tube G and the manner in which it is supported andoperated are fully shown in Figs. 7, 8, and 9. A is a cot umn that isbolted to the bedplate A. The

top of said column is of a ll-shape, and is ICO The

adapted tothe slide-plate R, the said slideplate having a circularprojection, s, which fits int a recess formed in the base of pillows T.The base of pillows T is secured to the slide-plate It by the nut f,eyebolt g, and spindle h. The end of spindle h (shown projecting intoeye of bolt is made eccentric to the other part of said spindle, andwhen the spindle h is turned partly around it either slackens ortightens the base of pillows T in relation to the slide-plate The baseof pillows T is circular, and has connected to it, by the bolts q, atail-piece, Z. The pillows T can be made to turn upon the slideplate R,the circular projection s guiding the base of pillows T, so as torevolve around the bolt 9 as a center. The tail-piece Z is furnishedwith a nut, S and two slide blocks, w, the said slideblocks beingpivoted from and on opposite sides of the nut S. The screw S is securedto the slide-plate R by two small pillows, 3 The screw S takes into thenut S, and when the screw S is turned around it causes the tail-pieceZto move either toward or from the operator, the slide-blocks w allowingthe tailpiece Z to be placed at different angles to the slide-plate It.The tail-piece Z being attached to the base of pillows T, and thespindle U being supported by the said pillows, whenever the tail-piece Zis changed in its position to the slide-plate B by turning around thescrew S the spindles m and U cause the face-plate Y and abrading-tube Gto change their positions accordingly, placing the abrading-tube G at adifferent angle to the tread of car-wheel. The hollow spindle U revolvesin the boxes 01' the pillows T, and between the pillows is abelt-pulley, V, that is made fast to the said spindle. The hollowspindle U has a spindle, m, fitting into it, both spindles revolvingtogether. A groove is cut in spindle on its entire length, and thespindle U has a tonguebolt, on, and the inner end of said bolt fits intothe groove formed in the spindle an. The

spindle m can be run in or out by the hand wheel \V, and as theabrading-tube G becomes shorter by wear the hand-wheel \V is graduallyturned around, so as to keep the face of abrading-tube G bearing uponthe tread of the car-wheel.

To the spindle m the face-plate Y is firmly attached, and to theface-pl: to Y theabrading-tube G. The abrading-tube G is secured to theface-plate Y by a number of bolts, j, the abrading-tube G having T-shaped slits for the heads of said bolts. The abrading-tube G isencircled by an adjustable tube, 7r, of iron or other metal. The tube k,as the abradingtube G wears away, can be occasionally forced back by theworkman, so as to cover more of the rim of face-plate Y, a smallset-screw, c, bein g used to retain the tube when adjusted in its place.I prefer the abrading-tube G to be an eighth of an inch smaller indiameter than the tube In, and the intervening space between theabrading-tube G and the tube 76 to it, one end of which is screwed in aplastic conbe filled with plaster-otparis solidifying comdition, orother equally quick position. the periphery of abrading-tube G lacksfrom a true circle, and is an expeditious method ot confining theabrading-tube G so that it IS firmly bound by the metal tube It, so asto pre vent the bursting of the abrading-tube G when revolving rapidly.The hand-wheel \V has a deep hub, and upon the hub are formed severalthrust-collars, i, the hub of handwheel revolving in pillow T. has ascrew out upon its inner periphery, and when the said hand-wheel isturned around it compels the thrust-spindle a, said spindle the spindlem, with its faceplate Y, to move out or in according to the directionthat the hand-wheel \V is moved. The thrnstspindle n has a bolt, 0,passing through tight into the spindle m,- or the spindle m and bolt 0can be welded together, the outer end of bolt 0 hav ing nuts 0. Thethrust-spindle a has a screw.- thread formed. upon it, the bore of thehub of hand-wheel W having a corresponding thread cut on its iieriphery,and asthe hub of hand wheel \V is confined in itsplace in the pillow Tby the thrust-collars 2', and the thrust-spin dle a prevented fromturning around in the bore of hub of hand-wheel W by the inner end oftonguebolt 2, working in a groove formed the entire length of spindle a,the spin This fills up all irregularities that The hub of hand-wheel NV"and through the r dle a must of necessity move 1n the direction I of itslength whenever the hand-wheel \Y is turned around, the said spindle amoving out or in according to the direction in which the said hand-wheelis caused to revolve, and the spindle n being confined between the innerend of spindle m and the nuts 0 on bolt 0, the spindle a mustnecessarily also move the spindle m, face-plate Y, and abradingtube Galon with it whenever the hand-wheel \V is caused to revolve.

Having described in detail the dilterent parts of my improved grindingand turning machine, the operation of the same is as follows: Thecar-wheels that require to be trued are first raised by the ram of thehydraulic jack to the height of the centers a of the driving-heads B,and the X16 of the car-wheels secured by the projecting centers at ofthe spindles O. Theaxle and car -wheels are then made to revolve bygiving motion to the belt-pulley F, which causes all the wheels,spindles, and shafts intervening between the driving-heads B and saidbelt-pulley to revolve according to the direct-ion of the acting force,and the corresponding wheels, pinions, and shafts of the driving-headsrevolve in the same direction and at the same rate of speed. The largeabradingtubes G are then given a revolving motion by their respectivebelt-pulleys V, and they, as hereinbefore described, can be adj ustcd togrind the treads of the carwheels to any required taper. The faces ofthe large abrading-tubes G are intended to be nearly the full breadth ofthe tread of carwheels, and when in operation the abradingtubes G alsocould be given a reciprocating transverse motion across the face ofcarwheels I by giving an alternate movement to the handle d, whichoperates the screw (1. The small abradingtubes K are given a rapidrevolving motion by their respective beltpulleys J and are intended towork equally well upon the tread or the flanges of the car-wheels. Theyalso can be placed at an angle to the flanges of the car-wheels, asalready described, and a curvilinear shape given to the flanges. InFigs. 1 and 2 only one small abrading-tube is shown. The other tube issupposed to be temporarily replaced by an ordinary steel turning-tool,I, as the machine can be used solely as a grindingmachine; or whencar-wheels with steel. tires are suspended from the centers a of thedrivingheads the machine can then be used as a turning lathe andgrindingmachine combined. The dust arising from the abrading-tubes andear-wheels is conveyed away by pipes that connect with an exhaustfan.
